As you are probably aware, diamonds are the hardest naturally occurring substance. Nothing can scratch a diamond. The hardness of a diamond is due to the bonds between the carbon atoms. On both the Vickers scale and the Moh’s hardness scale, diamonds are the hardest substance. However, diam...
Everything in the universe is made up of atoms, the universe is full of sound and we being part of the universe are therefore full of sound. The world of music and sound has no space and no time or limitations. Sound is one of the initial senses to awaken in the womb (子宫). It...
【题目】Everything on Earth that scientists can see,measure or study is made of atoms and atoms are named by what types of elements (元素)they are. You probably know the name of many elements, such as orygen or hydrogen. In any case, elements are everywhere: You, your -shoes, your ...
Many models that eloquently articulate arrangements of atoms and molecules to informed scientists are not widely understood by lay people and may promote naive notions among the public. Shifts from one type of atomic model to another and changes in size scales are particularly confusing to learners....

to makeuseful connections between different concepts, and thus is both endemic andessential. That point was emphasized, with particular reference to atoms andorbitals, in Ted Brown’s excellent discussion of metaphor in science:[A]ny model we might use to characterize the atom is metaphorical, ...
I can sense the gases, the solids, the liquids; the matter and antimatter; the bright firing of solar power and the brooding void of dark energy; the photons, ions, atoms, electrons, protons, neutrons, quarks, bosons, strings, and dots of miniscule existence. I can sense the presence of...
” This question may be answered by “listening in” to a large collection of very quiet atoms at the core of extremely sensitive radiation detectors installed deep underground. In this quiet environment we may be sensitive to the collisions of dark matter particles with ordinary atoms, and ...
where 𝛼𝑚αm is the m-th trajectory of the alpha particle and 𝜉𝑚ξm is the state of the excited atoms of the gas along that trajectory. The fact that when one atom is excited the probability is high for the next excited atom to lie on a straight line connecting the two fol...
